    Abstract : This thesis deals with the subject of lateral bracing between the bottom flanges of I-girder composite bridges. The focus is on the impact of adding lateral bracing on existing bridges, as well as on new bridges. READ MORE

  5. 8. Analytical Approaches to Load Modulation Power Amplifier Design

    Author : William Hallberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear; load modulated balanced amplifier LMBA ; Active load-pull; radio frequency RF ; Wilkinson power divider.; load modulation; energy efficiency; microwave; power amplifier PA ; Doherty;

    Abstract : In future mobile communication networks, there will be a shift toward higher carrier frequencies and highly integrated multiple antenna systems. The system performance will largely depend on the available radio frequency (RF) hardware. As such, RF power amplifiers (PAs) with improved performance, e.g. READ MORE

  6. 9. On Possibilities of Using Smart Meters for Compulsory Load Shedding Supported by Load Forecasting

    Author : Yasir Arafat; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power quality; Remote switching; Electrical distribution system; Smart meter; Compulsory load shedding; Load forecasting;

    Abstract : The smart meter rollout is progressing in several parts of the world with early adoption in some parts, e.g., Europe. Remote ON/OFF control switch of the smart meter allows distribution system operators to switch the smart meter of any customer remotely. READ MORE
